I have a '93 SL2 with 145,000 miles. When I use my air conditioner there is a creaking noise (like a door slowly opening in the horror movies) under the left rear of my car. This is easy to reproduce if I press down on the trunk. However, this only happens when I use the air conditioning, which is very rare, so I'm hoping that nothing is about to fall off. Could this be a heat issue? Any hints?
